I have a vector X of size 100x2 and the corresponding binary labels in a vector y ={1, -1} of length 100. I would like to plot the scattered data with s.t. I get the features on the axis and the color of the data point corresponds to a label e.g. red is -1, yellow is 1 for a given data point.
I've been looking into matplotlib and the fcn scatter however it accepts only a single feature vector and its label.
I would be grateful for any help.
You can do this easily using seaborn
(or matplotlib as well). Below is the code.
>> import numpy as np
>> X = np.random.randint(100, size=(100, 2))
>> Y = np.random.choice([0, 1], size=(100))
>> X
array([[11, 47],
[23, 2],
[91, 14],
[65, 32],
[81, 78],
....
>> Y
array([0, 0, 0, 1, 0, 1, 0, 0, 1, 0, 1, 1, 0, 1, 1, 0, 0, 1, 0, 1, 0, 1,
0, 0, 0, 1, 1, 0, 0, 1, 1, 1, 0, 0, 0, 1, 0, 0, 0, 1, 1, 0, 1, 0,
1, 0, 0, 1, 1, 1, 1, 1, 0, 1, 1, 0, 1, 0, 1, 1, 1, 1, 1, 0, 0, 1,
0, 0, 1, 1, 0, 0, 1, 1, 0, 1, 0, 1, 0, 0, 1, 0, 0, 1, 1, 1, 1, 1,
1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 1, 1])
Use Seaborn scatterplot
import seaborn as sns
sns.scatterplot(x=X[:,0], y=X[:,1], hue=Y)
Output sns scatterplot
